Question

A store manager timed Janette to see how long it would take her to fold and put away a sweater, a shirt, a pair of pants, and a scarf. It took her 26.1 seconds for the shirt, 24.3 seconds for the sweater, 32.8 seconds for the pants, and 18.2 seconds for the scarf. What was the average time it took Janette to fold and put away all four items?

Answer 1

The Average, or the mean of the times, is the sum of the times divided by the number of times. 

26.1 + 24.3 + 32.8 + 18.2 = 101.4
101.4 / 4 = 25.35 seconds.

25.35 seconds is the average

Answer 2

25.35 seconds. 
26.1+24.3+32.8+18.2=101.4
101.4/4 (the number of items)=25.35 per each item
